Determining the role of innovative teaching practices, sustainable learning, and the adoption of e-learning tools in leveraging academic motivation for students' mental well-being

Background
The prevalence of mental health issues among Chinese students is high, with depression, anxiety, and academic stress being some of the most commonly reported issues [1].As a result, there is a growing recognition of the importance of prioritizing students' mental well-being in China, with schools and universities seeking to implement measures to address these challenges [2].Despite the challenges, there are also growing efforts to promote mental health awareness and support among students in China.Schools and universities are implementing strategies such as providing mental health resources and support, promoting physical activity and healthy habits, and fostering a supportive and inclusive environment [3].By prioritizing the mental well-being of students in China, schools and universities can help ensure that students are better equipped to navigate the academic, social, and personal challenges they face, leading to improved outcomes and a brighter future [4][5][6].
Through the use of innovative teaching practices, educators in China can create a learning environment that is engaging, inspiring, and tailored to the needs of individual students.By emphasizing student-centered learning and the development of critical thinking and problemsolving skills, sustainable learning approaches can promote students' sense of autonomy and self-efficacy, leading to improved academic motivation and mental well-being [7].The adoption of e-learning tools, such as digital learning platforms and online resources, can also provide students in China with flexible and accessible learning opportunities that meet their individual needs and preferences.This can help to enhance students' engagement and motivation, leading to improved academic outcomes and greater well-being [7].
By leveraging these approaches, schools and universities in China can help promote the academic motivation and mental well-being of their students.This, in turn, can lead to improved outcomes for students, including higher academic achievement, better social relationships, and greater overall well-being.Given the importance of these issues, it is crucial that educators in China continue to explore innovative approaches to teaching and learning that can support the well-being and success of their students [8].
Many issues still need to be resolved despite the possible advantages of innovative teaching techniques, sustainable learning, and e-learning tools in fostering students' academic motivation and mental well-being.There are also worries about the potential detrimental impacts of excessive technology use on mental health, including a rise in social isolation and a shortening of attention span.Additionally, it's essential to ensure these procedures are fair and open to all pupils, especially those who might not have access to the required tools or resources.
More study and practical advice need on using innovative teaching practices, sustainable learning, and e-learning tools [9].
In recent years, interest shows how e-learning tools, sustainable learning strategies, and innovative teaching techniques can help students' academic motivation and emotional well-being.Researchers and educators are looking into novel ways to use e-learning tools to improve students' learning outcomes and well-being due to the growing use of technology in education.Additionally, being researched to encourage more excellent Learning and boost engagement are sustainable learning practices like offering ongoing support and feedback [10].Furthermore, it acknowledges that promoting one can benefit the other because academic motivation and mental health are closely related.As a result, there is a need to comprehend more fully how e-learning tools, sustainable learning, and novel teaching techniques can support student motivation in the classroom and advance mental health [11].
Self-Determination Theory (SDT) is a crucial theoretical framework for comprehending how creative teaching methods, long-term learning strategies, and online learning resources encourage students' academic motivation and emotional health.SDT strongly emphasizes the role that intrinsic drive, autonomy, and competence play in fostering long-term learning and well-being.Educators can support the development of intrinsic motivation and involvement in the learning process by giving students the freedom to choose and take charge of their learning and encouraging a sense of competence and mastery [12].SDT also acknowledges that each student has unique needs and motivations and those successful teaching strategies should adjust to meet those needs.It is essential in online learning, where tools like flexible learning technologies can make it easier to create personalized learning experiences.In brief, educators can support the development of sustainable learning, academic motivation, and mental health in their students by incorporating SDT principles into the design and implementation of cutting-edge teaching methods and e-learning tools [13].
Academic motivation is the urge or desire to carry out educational tasks like learning, studying, and achieving academic objectives.The academic motivation that comes from within a person rather than outside influences like rewards or penalties is intrinsic.A sincere interest in and pleasure in learning, as well as a desire to master new abilities or knowledge, are characteristics of intrinsic motivation [14].Learning is motivated by the intrinsic fulfillment and satisfaction of participating in the learning process.Since intrinsic motivation promotes a love of Learning and a sense of autonomy and competence, it thinks to be more long-lasting and advantageous for long-term academic success and mental health [15].
Students' mental well-being is a state of emotional, psychological, and social well-being that allows them to manage the demands and pressures of academic life, uphold healthy interpersonal relationships, and engage in healthy behaviors.It entails having self-assurance and competence in one's intellectual abilities, successfully handling stress and anxiety, and keeping a positive outlook on life [16].Several variables, such as academic success, social support, physical health, and accessibility to tools and support services, impact students' mental well-being.Educators and institutions must prioritize students' mental health to foster academic achievement, personal development, and general well-being (17).
"Sustainable learning" refers to a teaching method emphasizing the effectiveness and long-term effects of learning activities and results for individuals and society.It entails creating and implementing educational opportunities that support moral and ethical behavior and environmental, social, and fiscal sustainability.Students must have the information, skills, and attitudes to handle present and future sustainability-related challenges, such as climate change, social inequality, and economic development [18].This method also acknowledges how interconnected various sustainability components are, and it aims to incorporate environmental, social, and economic considerations into every element of the learning process.Education for Sustainable Development (ESD), which seeks to empower people, includes sustainable learning as a crucial component [19].
Using technology-based tools and materials in the teaching and learning process refers to adopting e-learning tools.Digital technologies and platforms like learning management systems (LMS), video conferencing, multimedia content, and educational applications are all included in the category of "e-learning tools." To better learning outcomes and access to education, e-learning tool adoption entails integrating these technologies into educational practices and strategies [9].It gives students a chance to access educational content remotely and at their own pace, and it gives teachers the tools they need to design and execute specialized learning experiences.In addition to lowering the costs associated with conventional education delivery, adopting e-learning tools can improve teaching and learning efficacy and efficiency [20].
Innovative teaching is a dynamic and creative strategy for education that goes beyond conventional approaches and promotes the use of fresh, cutting-edge tactics to engage and inspire students.It entails developing and putting into practice teaching strategies that are engaging, participatory, and student-centered, as well as a variety of cutting-edge technological and pedagogical approaches [21].Innovative teaching strongly emphasizes allowing students to participate fully in learning and hone their collaborative, critical thinking, and problemsolving abilities.Additionally, it promotes the inclusion of various viewpoints and experiences in the learning setting and works to develop a welcoming and inclusive classroom culture.Innovative teaching has the potential to better prepare students for the demands of a world that is changing quickly while also increasing the efficacy and relevance of education [22].
One of the weaknesses in the research is that sociocultural factors that may affect students' motivation and mental health do not consider.Despite being crucial components of a modern educational system, innovative teaching methods, sustainable learning, and e-learning tools, their efficacy may differ based on the students' cultural background, social mores, and religious beliefs.Another flaw is the study's narrow emphasis on the effects of progressive teaching methods, lifelong learning, and e-learning tools on particular student groups [23].The study must consider the distinct learning requirements of various student groups, such as those who are disabled or come from low-income backgrounds.For instance, students with visual or hearing impairments might be unable to use e-learning tools, so the research needs to consider these constraints and offer alternatives.The study must also address the potential adverse effects of e-learning tools, including increased screen time and potential harm to students' mental health.Even though e-learning tools can improve motivation and the learning process, excessive use of digital devices can worsen stress, anxiety, and other mental health problems [24].The research must therefore offer suggestions for reducing these adverse effects and fostering a positive balance between technology use and mental health.
The existing gap in research lies in a comprehensive understanding of the interplay between innovative teaching practices, sustainable learning approaches, and the integration of e-learning tools in fostering academic motivation and subsequently contributing to students' mental well-being.While individual studies have explored these elements in isolation, there is a need for a cohesive investigation that examines their combined impact on student motivation and mental health.The objective of this research is to bridge this gap by conducting a holistic examination of how innovative teaching methods, sustainable learning strategies, and the effective use of e-learning tools collectively influence academic motivation, with a particular focus on their implications for enhancing students' mental well-being in educational settings.

Self-determination theory
This theory strongly emphasizes the value of intrinsic drive in fostering long-term learning and mental health.
Students intrinsically motivated to learn are more likely to persevere in their academic endeavors and feel more satisfied with their learning [25].Students have better outcomes about their mental health, claims SDT. Innovative teaching methods and e-learning resources that offer chances for autonomy, competence, and relatedness can aid in fostering intrinsic drive and advancing long-term learning [26].

H1: Academic motivation has a positive impact on mental well-being.
Academic achievement depends heavily on academic motivation, which is associated with many beneficial effects, including mental health.Academic motivation and psychological well-being have been the subject of numerous studies, and the findings have generally supported the notion that students who are more motivated academically tend to have greater levels of psychological well-being [27].For instance, pupils who more academically drive exhibited more significant self-esteem, a positive outlook, and lower levels of anxiety and depression.Comparing students whose motivation was more controlled to those who were more autonomous; it finds that the latter claimed greater well-being.Researchers found that mastery-oriented students had better levels of psychological well-being than performance-oriented students in terms of academic motivation [28].Last but not least, a meta-analysis revealed that academic motivation favorably correlates with academic success and psychological well-being, with intrinsic motivation showing the strongest correlations [29].These studies show that academic motivation can improve mental health, especially when autonomous, mastery-oriented, and intrinsic.

H2: Academic motivation can lead to sustainable learning.
More recent studies have continued to investigate this connection, despite the abundance of literature on the beneficial effects of academic motivation on long-term learning.According to one of these studies, pupils with high levels of intrinsic drive demonstrated more sustained learning behaviors, such as regular attendance at school, systematic study, and asking for assistance when required.According to the authors, this might be because intrinsically driven students have a greater sense of autonomy and control over their learning, enabling them to make better choices about how to approach their studies [29].According to another research, learners motivated by academic mastery exhibited higher self-control, perseverance, and self-efficacy.According to the authors, this might be the case because mastery-oriented students are more concerned with improving their knowledge and abilities, which results in a more enduring approach to learning [30].Furthermore, a study discovered that academic motivation, primarily intrinsic and goal-oriented, was positively associated with long-term learning.Because intrinsic motivation links to a greater [27].
These recent studies confirm that intrinsic, masteryoriented, and goal-oriented motivation in the classroom positively affects long-term learning.These studies emphasize the significance of encouraging students' academic motivation to support long-term academic achievement and sustainable learning behaviors.

H3: Academic motivation can foster the adoption of e-learning tools.
Their academic motivation positively impacts the use of e-learning tools by pupils.Technology-based teaching and learning aids, including online classes, videos, simulations, and virtual reality, are e-learning tools.According to research, university students' use e-learning tools positively correlate with their study motivation.According to the authors, students more interested in their academic work may be more ready to experiment with and use new technologies to improve their learning [31].According to the results of another study, students who were highly motivated academically were more apt to use e-learning resources and were happier with their e-learning experiences.The authors speculate that this might be the case because students motivated by their studies are more likely to look for additional resources and participate in self-directed learning, which e-learning tools can aid [32].In addition, research showed that university students' perceptions of the usefulness and simplicity of e-learning tools positively correlate with their academic motivation.According to the authors, this may be because academically driven students are more likely to approach e-learning tools to achieve their educational goals and are thus more likely to perceive them as helpful and simple to use [33].
These studies indicate that academic motivation influences students' use of e-learning tools favorably.Teachers may be able to encourage the use of e-learning tools to improve learning outcomes and foster student involvement by encouraging academic motivation in their students.

H4: The adoption of e-learning tools has a positive impact on sustainable learning.
Adopting e-learning resources has also been discovered to have a favorable effect on pupils' long-term learning.Learning habits sustained over time and resulting in long-term academic achievement are called sustainable learning.According to a study, using e-learning tools was favorably related to long-term learning habits like time management, self-control, and persistence.The authors contend that by giving students flexible and convenient access to learning materials and chances for self-directed learning, e-learning tools can promote sustainable learning [34].Another study discovered a positive correlation between using e-learning tools and student involvement and academic success, which are crucial in encouraging long-term learning.The writers contend that interactive, personalized learning experiences for students can help to promote sustainable learning by increasing their motivation and engagement [35].
Additionally, the researchers discovered a positive correlation between using e-learning tools and academic self-efficacy, a crucial element in encouraging long-term learning.The authors contend that by giving students chances to practice and implement their knowledge and by giving them feedback on their advancement, e-learning tools can foster academic self-efficacy.

H5: Sustainable learning practices can lead to mental well-being.
Students' emotional health finds to improve as a result of sustainable learning.Learning habits sustained over time and resulting in long-term academic achievement are called sustainable learning.According to research, stress and anxiety levels were lower among students who practiced sustainable learning behaviors like efficient time management, self-regulated learning, and seeking assistance when required.By lowering the perceived demands of academic tasks, enhancing students' feeling of control over their learning, and boosting their confidence in their ability to handle academic challenges, the authors contend that sustainable learning can improve mental well-being [36].According to other research, students who practiced sustainable learning habits like time management and self-regulated learning had higher academic self-efficacy.The authors contend that sustainable learning can enhance psychological well-being by encouraging a sense of accomplishment, raising students' perceptions of their own competence, and encouraging the positive feelings connected to effective learning [37].
Additionally, a study found that self-regulated learning and efficient time management were positively related to academic achievement and engagement, which are crucial components in fostering mental well-being [29].According to the authors, sustainable learning can improve mental health by giving students a sense of direction and purpose, increasing their engagement with scholastic work, and fostering a sense of competence and mastery [25].

H6: The adoption of e-learning tools has the potential to positively impact mental well-being.
Adopting e-learning resources has also been discovered to have a favorable effect on students' emotional health.Digital tools and platforms that make it easier to study and teach online refer to as e-learning tools.According to a study, students' mental health correlates with using e-learning resources.The authors contend that by giving students flexible and available learning opportunities, lowering commuter and scheduling-related stress, and improving the overall learning experience, e-learning tools can support mental health [38].According to further research, using e-learning resources was associated favorably with psychological well-being, satisfaction with the learning process, and perceived Learning outcomes [31].The authors contend that by giving students a sense of agency over their education, boosting their motivation and engagement, and encouraging the good feelings linked to effective learning, e-learning tools can support psychological well-being [32].
Additionally, the researchers discovered that using e-learning tools was positively associated with academic performance, which is crucial in encouraging students' mental well-being.According to the authors, using e-learning tools can improve students' academic performance, increase their sense of competence and mastery, less stress related to academic challenges, and foster good emotions related to academic success [39].

H7: Sustainable learning acts as a mediator between academic motivation and mental wellbeing, thus, facilitating the positive relationship between the two.
According to recent studies, the connection between students' academic motivation and mental health can mediate by sustainable learning.The term "sustainable learning" refers to actions that support effective and efficient learning, such as time management skills, self-control, and asking for help when necessary [40].According to research, university students' academic motivation positively correlates with long-term learning and mental health.As a result, more academically motivated students may engage in more sustainable learning behaviors, supporting their mental well-being [41].The authors speculate that sustainable learning may act as a mediator between academic motivation and mental well-being.Furthermore, a survey of undergraduate students revealed that sustainable learning behaviors mediated the link between scholastic stress and mental health.According to the authors, students who engage in sustainable learning practices may be better prepared to manage their stress and maintain their well-being, which may mitigate the detrimental effects of academic stress on mental health [42].
These results emphasize the value of sustainable learning in encouraging students' mental health and imply that sustainable learning may function as a mediator in the connection between academic motivation and mental health.Teachers and lawmakers can support students in becoming more academically motivated, mentally healthy, and successful by encouraging sustainable learning behaviors.

H8: The adoption of e-learning tools acts as a mediator in the relationship between academic motivation and mental well-being, thus, facilitating positive relationship between the two.
Recent studies have also indicated that using e-learning resources may mediate the connection between students' mental health and academic motivation.Online learning management systems, virtual classrooms, and educational apps are just a few examples of the digital tools and platforms known as "e-learning tools" that make learning and instructing easier [43].According to research, among Brazilian high school pupils, e-learning tools mediated the connection between academic motivation and mental health.According to the authors, using e-learning tools may improve academic motivation by giving students more exciting and interactive learning opportunities, which can improve their mental health [44].In addition, a survey of university students in China discovered that the use of e-learning tools mediated the relationship between academic stress and mental health.The authors contend that e-learning resources may give students more freedom and control over their education, which can lessen academic pressure and improve mental health [45].
These results imply that e-learning tool adoption may mediate between academic motivation and mental health.E-learning tools may boost academic motivation and lessen academic tension by giving students more flexible and engaging learning opportunities, which can improve students' mental health.

H9: The adoption of e-learning tools acts as a mediator in the relationship between academic motivation and sustainable learning practices, thus, facilitating the positive link between the two.
According to recent research, the adoption of e-learning tools may act as a mediating factor in the connection between student academic motivation and long-term learning.Sustainable learning behaviors include time management, self-regulation, and asking for feedback that promotes effective and efficient learning [46].According to a study among Chinese university students, adopting e-learning tools mediated the connection between academic motivation and long-term learning.The authors contend that by giving students more engaging and interactive learning opportunities to encourage their long-term learning habits, e-learning tools may improve academic motivation [47].Similarly, a study of university students in Jordan discovered that adopting e-learning tools mediated the link between self-efficacy and sustainable learning.The writers contend that by giving students more chances for active and independent learning, which can, in turn, encourage their long-term learning habits; e-learning tools can improve students' sense of self-efficacy [48].These results imply that e-learning tool adoption may mediate between academic motivation and long-term learning.E-learning tools may boost students' academic motivation by giving them more interactive and engaging learning experiences, which may encourage long-term learning habits.

H10: Innovative teaching practices play a moderating role in the relationship of academic motivation and mental well-being in a way that these practices enhance the positive effects of motivation on well-being.
According to recent research, the connection between student academic motivation and mental health may moderate by creative teaching strategies.Project-based learning and blended learning increase students' motivation and involvement.A study of Chinese high school students showed that innovative instruction influenced the relationship between academic motivation and mental health.According to the authors, creative teaching methods can help students become more motivated to learn by encouraging their interest, curiosity, and ingenuity, all of which can help students' mental health [49].Similarly, a study of university students in China discovered that creative teaching influenced the connection between academic stress and mental health.By giving students more engaging and encouraging learning opportunities, innovative teaching strategies, according to the authors, can help lessen scholastic stress and improve students' mental health [50].
These results imply that creative instructional strategies may moderate the relationship between academic motivation and mental health.Innovative teaching strategies may boost students' motivation for learning and lessen the damaging impacts of academic stress on their mental health by increasing their engagement, interest, and creativity.

H11: Innovative teaching practices play a moderating role in the relationship of academic motivation and sustainable learning in a way that these practices strengthen the positive effects of motivation on sustainable learning.
According to a recent study, the relationship between academic motivation and long-term learning among students may moderate by creative teaching strategies.According to research, among Chinese college students, innovative teaching mediated the relationship between academic motivation and long-term learning.The authors contend that creative teaching methods can increase students' motivation for academic work by encouraging their interest, curiosity, and creativity, promoting long-term learning habits.A similar study among Chinese university students discovered that innovative teaching moderated the link between academic self-efficacy and long-term learning [51].The authors contend that by giving students more opportunities for active and autonomous learning, innovative teaching strategies can raise students' academic self-efficacy and encourage long-term learning habits [49].These results imply that creative instructional strategies may moderate the relationship between academic motivation and long-term learning.Innovative teaching strategies may promote students' academic motivation and support their sustainable learning behaviors by raising their engagement, interest, and creativity [52].
In conclusion, creative teaching strategies can be a significant moderator in the connection between student academic motivation and long-term learning.Educators and policymakers should consider encouraging innovative teaching approaches in their educational programs and interventions geared at boosting students' academic motivation and promoting their sustainable learning behaviors.

H12: Innovative teaching practices play a moderating role in the relationship of sustainable learning practices and mental well-being in a way that these practices enhance the positive effects of sustainable learning on well-being.
The idea that creative instruction modifies the link between long-term learning and mental health support several studies.Innovative teaching strategies can increase students' enthusiasm and engagement in their studies, resulting in long-lasting learning habits.These actions link to improved mental health outcomes, including lower stress and anxiety levels and higher life happiness [53].Project-based learning and student mental health were the subjects of one research.According to the research, project-based learning was linked favorably to long-term learning habits and outcomes related to mental well-being [30].More specifically, participants reported higher degrees of mental well-being.Different research looked into the connections between gamification, student motivation, and mental health Additionally, it discovers that student incentives moderated the association between gamification and mental health.Students who reported being more motivated by the gamification strategy, in particular, expressed more significant levels of mental well-being [53].
According to these results, creative teaching strategies can improve long-term learning habits, benefiting students' mental health.Furthermore, variables like student motivation and engagement may be moderators in these relationships.Educators and policymakers should consider incorporating innovative teaching techniques into their curricula.Based on the above literature, the following hypothetical model is presented in Fig. 1:

Population, sampling and data collection
The current study adopted the quantitative research design because the basic purpose was to test the existing theory by investigating the causal relationships among the variables of interest [54,55].This study was based on a survey questionnaire designed to obtain information from international students studying in Chinese universities.Students were mainly recruited from Tsinghua University, Peking University, Shanghai Jiao Tong University, Zhejiang University, University of Science and Technology of China.These universities are reported to have no international students [56].The universities were selected through convenience sampling.That is, the researchers selected the universities which they could easily obtain permission to enter.It is believed that international students develop various mental illnesses due to cultural and life style differences [56] especially after COVID and need immediate attention from authorities.In order to collect data related to the variables of the study, universities were contacted for the collection of initial information about the total no. of international students, for permission to contact these students and to discuss the objectives of the study.Based upon initial discussion, it was decided to share the research instrument with the university administration for the collection of data through student help desks / and graduate centers.
Importantly, the questionnaire was composed of two sections, first section was related to the explanation of the scope of research and the collection of demographic information.The second section contained 27 pertinent questions about the main variables of the study.The researcher sent questionaries to 384 participants, the required sample size.However, only 308 respondents completely answered to the items of all questionnaires.
As there was no missing data, responses from these 308 questionnaires were utilized for further analysis.

Instruments
It can be seen that the current research is limited to the assessment of direct, indirect and moderated effects among five different observed variables i.e., academic motivation, mental well-being, sustainable learning, adoption of e-learning tools and innovative teaching (see Fig. 1).A standardized questionnaire was used to collect data from the respondents i.e., students.The items of the questionnaire were adapted from the published literature; 6 items of academic motivation adapted from.Kotera, et al. [57], 4 items of sustainable learning adapted from Islam [58] and McDowall and Jackling [59], 4 items of adoption of e-learning tools adapted from Cho, et al., [60], 6 items of innovative teaching adapted from Tan, et al. [61] and 7 items of student mental well-being adapted from Anthony, et al., [62].To collect data using these questionnaire items, this research employed 7-point Likert scale ranging from 1 to 7 (1 = Not at all to 7 = Very much).All instruments enjoyed high level of internal consistency as Cronbach's alpha for each scale exceeded 0.70.The scales also had acceptable divergent and convergent validity (See the results section).

Data analysis
This research used the famous software "Mplus" for the analysis of the data, therefore, it was essential to assign short names to the variables.For that purpose, various codes / short names were assigned to the variables of the study in order to keep the variable names lesser than 8 characters [63] and each line of the input lesser than 90 characters [64].Therefore, for effective data handling, the names of variable "academic motivation" was changed to ACM, mental wellbeing was changed to "MW", sustainable learning was renamed as "SUSL", adoption of e-learning tools was renamed as "AEL" and the moderating variable's name "innovative teaching" was changed to "INNOT".
As the objectives of this research were to figure out the direct link between ACM and MW, indirect link via SUSL and AEL, and the moderating effect of INNOT on various paths (ACM-SUSL, ACM-MW, SUSL-MW).
To achieve these objectives, data was collected from 308 students and multiple preliminary assessments were made prior to hypothesis testing i.e., descriptive statistics, analysis of correlations, assessment of model fitness.For hypothesis testing, structural equation modeling approach was applied using a frontline software "Mplus" [64].Before submitting the data to the inferential statistics, we checked whether the data were normally distributed.As seen in Sect.4.3, the data were normally distributed and we felt sure that this assumption was not violated.

Assessment of model fitness
Confirmatory factor analysis was run to examine the various model fit-indices provided in Mplus output.Notably, as the study aimed to test the existing theory and focused on deductive reasoning, it was essential to conduct CFA) using Mplus 7 [64].We examined various model fit-indices, including, chi-square, SRMR, RMSEA, CFI, and TLI provided in Mplus output of CFA [57]and were compared with the threshold values [65][66][67].It was observed that the values of the fit indices were well within acceptable ranges (see Fig. 2; Table 1).

Assessment of validity, reliability and correlation
We first calculated discriminant validity and convergent validity [68] in order to confirm that the scale items were measuring the same concepts for which they were designed.To simplify, discriminant validity attempts to examine whether there is a good discriminant degree between different variables of the study [69].To achieve this purpose, average variance extracted (AVE) of the constructs was calculated along with the correlation between the constructs [70].It is recommended for each variable, that the square root of the AVEs should be greater than any of the correlations involving the said variables [70], which is the case here (see Table 2).Thus, the results indicate that the measures used in the study have discriminant validity.
In terms of the convergent validity of the constructs, it is argued that the designer of the questions of the questionnaire should have the same understanding on what the constructs intend to measure [68,69,70].It was observed that the factor loadings were higher than 0.5 (74) and the p-values of the corresponding items were lower than 0.05, indicating the acceptability of convergent validity.In addition to this, we also examined the values of AVE as part of the assessment process of convergent validity.The results demonstrated that the values of AVE were significantly higher than the recommended value i.e., 0.5 [71]), thus, confirmed that the coefficients of AVE satisfied the conditions of acceptable validity [71] (see Table 2).
Furthermore, in order to estimate reliability of the scale, composite reliability was calculated.The analysis revealed that the CR for all the variables was significantly higher than 0.7.Therefore, it was proved that the scale was completely reliable (see Table 2).

Analysis of descriptive statistics
Prior to the assessment of hypothesis, it was mandatory to find out that the data is normally distributed and the assumption of normality is not violated [72,73].To confirm this, mean and standard deviation from the mean    was computed.It can be seen (see Table 3) that the mean values of vary from 6.375 to 4.776.Similarly, the highest value of standard deviation from the mean remained 1.180 and the lowest value remained 0.757 to be precise (see Table 3).These values confirmed the normality of the data and indicated that the data is ready for hypothesis testing.

The assessment of common method bias
This research employed a structured questionnaire to gather the data at the same time and from the same participants, common method variance might represent a problem.To root out the potential problem a test of CMV conducted [73] using Harman's single-factor method [74].Therefore, by applying the Harman's test, it was found out that a single factor explained only 34.86% of the explained variance.The findings form these analytical procedures confirmed that CMV was not present and therefore did not influence the results [75].
Next, this section provides information about the specific indirect effects involving SUSL and AEL between ACM-MW path and between ACM-SUSL path.Table 5 provides detailed information about these effects.However, the significance of the indirect paths was particularly determined by using the p-value and t-value of the effects.Additionally, the mediation was further confirmed by analyzing the 95% ULCI and LLCI of the specific indirect effects of the said paths [75,76].Researchers are of the view the that the sample size should be replicated by at least 1000 bc-bootstraps for obtaining the reliable results of mediations [77] and for reliable confidence intervals [78].However, to be on the safer side, researchers have replicated the sample size by 2000 bc-bootstraps for obtaining results of mediated paths.Results are presented in Table 5.
Table 5 presents information about the specific indirect effects, wherein H7 examined the indirect link between ACM-MW path via SUSL.As highlighted in the above table, the indirect effect proved to be insignificant, i.e., β = 0.027, SE = 0.015, t-value = 1.81 and p-value = 0.070 (see Table 5).Additionally, confidence interval (95%) also proved the insignificance of the path because the upper and lower values passed through zero − 0.002-0.052[75,76].Therefore, it was concluded that H7 did not support the prediction of the researchers.H8 aimed to investigate the indirect effect of AEL between ACM-MW path.Results demonstrated that AEL significantly linked the ACM-MW path, β = 0.118, with SE = 0.031, t-value = 3.875 and p-value was 0.000.In addition to this, the significance of the mediated effect was also examined by observing 95% of CI, which did not pass through zero i.e., 0.068-0.169.Therefore, H8 was supported.H9 was the final hypothesis related to the assessment of mediation.The analysis revealed that AEL positively and significantly mediated the effect of ACM on SUSL, β = 0.123, with SE = 0.032, t-value = 3.847, p-value = 0.00 and 95% of CI = 0.071-176.These results supported the assumption of researchers, therefore, H9 was supported.
Likewise, this research had 3 hypotheses (H10, H11, & H12) which assessed the effect of moderating variables.Whereas, H10 investigated the moderating effect of INNOT on the path involving ACM-MW.The results showed the significance of the moderating effect of INNOT as the interaction effect was positive and significant i.e., β = 0.172, SE = 0.074, t-Value = 2.33 p-value 0.02.The moderation effect was further confirmed through the analysis of 95% CI and it can be seen that the upper and lower limits of 95% did not include zero i.e., 0.051-0.294.These results proved that H10 was supported.Similar to this, H11 and H12 examined the moderating role of INNOT on the ACM-SUSL path and SUSL-MW path respectively.The interaction effect proved the significance of the moderation on ACM-SUSL path i.e., β = 0.287, with SE = 0.098, t-value = 2.942 and p-value was 0.003 (See Table 6).
Moreover, the implementation of e-learning resources emerges as a positive influence on students' emotional health, aligning with the flexibility and accessibility these tools provide.E-learning tools afford students opportunities for flexible and accessible learning, increasing motivation, engagement, and fostering positive emotions linked to successful learning.Furthermore, the use of e-learning resources can mitigate the stress associated with scheduling and commuting, contributing to overall improved mental health.The sense of control over their education provided by e-learning resources is identified as particularly crucial for psychological well-being [17,32].While our research did not find direct support for the idea that sustainable learning mediates the link between academic motivation and mental health, it is essential to acknowledge the extensive body of literature indicating a positive correlation between academic motivation and outcomes related to mental well-being [5,21,46].The absence of a discernible mediating role for sustainable learning in this relationship suggests that while both factors independently contribute to mental health, they may not operate as direct mediators of each other.
Conversely, our findings strongly support the notion that sustainable learning significantly mediates the link between academic motivation and mental well-being, corroborating existing research [13,22,44].This underscores the importance of encouraging sustainable learning practices in educational settings, as they can lead to favorable outcomes, including reduced stress levels and increased academic satisfaction.Additionally, the lack of support for the idea that adopting e-learning tools mediates the link between academic motivation, sustainable learning, and mental well-being highlights the need for further investigation into the intricate relationships among these variables [17,32,44].
A crucial moderating factor identified in our study is the role of innovative teaching strategies in the connection between academic motivation and both sustainable learning and mental well-being.The results indicate that innovative teaching strategies can enhance students' interest and engagement in the learning process, thereby improving academic motivation and supporting longterm learning habits [18,38,52].This finding underscores the significance of integrating innovative teaching strategies into learning environments to enhance student engagement, motivation, and overall well-being.However, our research did not find support for the idea that innovative teaching moderates the relationship between sustainable learning and outcomes related to emotional well-being [38,51,58], suggesting that the impact of innovative teaching may vary across different aspects of mental health.
In conclusion, while our study provides valuable insights into the relationships between academic motivation, sustainable learning, e-learning tools, innovative teaching, and mental well-being, it is crucial to acknowledge the complexity of these interactions.The broader body of research in this field should be considered, and further studies are warranted to fully comprehend the intricate relationships among these variables .

Conclusion
According to our review, there is a significant connection between student outcomes for emotional well-being and academic motivation, sustainable learning, use of e-learning tools, and adoption.There is consistent evidence to support the notion that academic motivation, sustainable learning, and adoption of e-learning tools can promote good mental well-being outcomes, even though there is some variation in the strength and nature of these relationships across studies.Our research did not support the hypothesis that innovative teaching or sustainable learning mediates or modifies the relationship between academic motivation and mental health.It indicates that while innovative teaching and sustainable learning are essential for fostering academic success might not always be the main factors influencing outcomes conducive to mental well-being.Overall, our research shows how crucial it is to encourage academic motivation, lifelong learning, and using e-learning tools as part of a holistic strategy for promoting positive mental health outcomes in students.Additionally, it's crucial to keep researching the intricate connections between these variables and consider the environmental elements that might affect students' well-being.Educators and lawmakers should collaborate to develop and implement evidence-based strategies to support academic motivation, sustainable learning, and adoption of e-learning tools to promote positive mental well-being outcomes for all students.

Policy and practical implications
Several policy conclusions can make in light of the results to support student mental well-being in China.First, as part of a holistic strategy to encourage academic motivation and long-term learning, policymakers should place a high priority on the adoption of e-learning tools and cutting-edge teaching techniques.To make integrating e-learning resources and advanced teaching techniques into the classroom easier, this can include investments in technology facilities and teacher training programs.
The promotion of sustainable learning methods that adapt to the unique cultural and pedagogical context of China is also necessary.It may involve techniques to increase student motivation and engagement, like individualized learning plans and hands-on learning chances.Finally, policymakers ought to give top priority to the creation of strategies that are supported by data and that aim to improve students' emotional health.It may entail spending money on mental health resources, assistance programs, and campaigns to lessen stigma and raise awareness of mental health problems.
Overall, these policy ramifications highlight the significance of adopting a thorough strategy to encourage good mental well-being results among students in China.Policymakers can contribute to creating a supportive and empowering learning environment for all students by prioritizing academic motivation, sustainable learning, adoption of e-learning tools, and investment in evidencebased strategies to encourage good mental well-being outcomes.

Practical implications
Innovative teaching methods, lifelong learning, and e-learning tools have numerous practical applications for fostering academic motivation for students' mental health.It is essential to provide accessible and exciting learning materials.Students can access multimedia resources, interactive learning activities, and gamification techniques through novel teaching methods, sustainable learning, and e-learning tools, which keep them interested and motivated throughout their educational journey.
Another practical implication that can improve academic motivation and mental health is encouraging active learning.Students can take charge of their learning, feel competent, and feel connected by cooperating with others using sustainable learning techniques like projectbased learning, problem-solving, and teamwork.Thirdly, e-learning resources like online discussion boards, digital portfolios, and collaborative tools can allow students to connect socially with their classmates and teachers.As a result, there is a more incredible feeling of community, less loneliness, and better mental health.

Limitations
One drawback is that not all students have equal access to technology and online learning resources, which could lead to a digital gap and exacerbate already-existing disparities in academic motivation and mental health.Additionally, not all students may find online learning attractive or comfortable.Insufficient social contact in these settings may affect students' feelings of relatedness and belonging.Further, adopting innovative teaching methods and sustainable learning strategies might take a lot of time and money, and students and teachers might resist change.Although these methods may offer several advantages, it is essential to consider both their drawbacks and possible implementation difficulties.
